So what i have is prevalue source which is bunch of umbraco nodes. Each of these nodes has some data namely media picker with images. I have created my own view/form/FieldType.RadioButtonList the code for it looks like

<input data-val-defaultImage="@industryStandardImg" data-val-userAnswerImage="@GetImage(pv.Id)" type="radio" name="@Model.Id" id="@string.Concat(Model.Id,"_",pv.Id)" value="@pv.Value" 

The extra data attributes correspond to some images userAnswerImage is the image set on the answer node which is a source for the prevalues. The defaultImage is image set on the parent question node.

This all works fine and form renders no problem. So what I need to do is the following, after submitting the form on my thank you page i need to get the values on the attributes for the selected radios. Is there a way for me to do that maybe query post object? I need these values because on the thank you page depending on answers selected we will show bunch of images. Or do I hijack a route? Any ideas?
